To avoid obsolescence, the publisher of Pulmonary and Critical Care Medicine promises to send the purchaser, free of charge, any material needed to bring these two large, heavy, loose-leaf volumes up to date and to make available annual updates that will replace or add to the existing material with information and insights at the leading edge of these rapidly expanding fields. Dr Bone, his four associate editors, and the many contributors to Pulmonary and Critical Care Medicine present an enormous amount of useful, pertinent, interesting, and thought-provoking information.

In his overview of the subject, Bone discusses the relationship between muscle fatigue and respiratory failure.
